CARPENTERS GAG E1 SPECIFICATION formingpart of Letters Patent No.242,096, dated May 24., 1881,

Application filed March 12, 1881. (ModeL) To'all whom it may concern.-

Be it known that I, WILLIAM A. JAMES, of

Galena, in the county of Jo Daviess, and in applicable to the ordinarygage or to mortisegages. 4

The invention has for its objects to provide a means whereby the bar ofthe gagemay be more readily and conveniently traversed along the surfaceof the timber, as more fully hereinafter'specified. These objects Iattain by the mechanism illustrated in the accompanying drawings, inwhich- Figure 1 represents a bottom view of my improved gage. Fig. 2indicates a transverse section of the gage on the line so a: of Fig. 1,and

Fig. 3 a view of the forward end of the gagebar. a

The letter A indicates the bar of the gage,

which is rectangular in cross-section, as usual.

' The letterB indicates the slide, which is con- 0 structed in theordinary manner and fitted upon the bar in such a way that it may bereadily moved back and forth upon the same. The

said slide is provided with the usual set-screw,

O, by means of which it may be clamped in any desired position. Thelower side of the bar is provided with one or more longitudinal grooves,D, semi-cylindrical in cross-section.

The letter E indicates a roller, one being provided for each groove, andextending longitudinally through the same, being journaled at oppositeends in hearings in the plates F G. The forward plate has a verticalaperture, H, through which is passed the forward marker, I, which isadjustable in said aperture.

In the presentinstance the apparatus is rep- 5 sented as a mortise-gage,and is provided with two rollers. Between the rollers is formed alongitudinal groove, K, in which is adapted to slide a bar, L, whichcarries at its forward end a marker, M. The said bar, at its rear, endis provided with a button or projection, N, by which it may be adjustedin its groove.

The operation of my improved gage will be readily understood, inconnection with the above description, withontfurther explanation. 5 5

Having thus described my invention, what Iclaim, and desire to secure byLetters Patent, is

In combination with the bar A, provided with rollers, as described, theadjustable marker 1, 6o sliding marker M, secured to bar N, and theslide B, all arranged substantially as specified.

In testimony that I claim the foregoing I have hereunto set my hand this2d day of I March, 1881.
